The three-dimensional figures normalized representation is performed on the teachings of Drafting, mainly during the school, can be proposed from still images, solid or animated images represent models. Depending on the complexity of the model and the learning phase in which the student is… (leer más)
An interesting piece in 3d mechanical, useful mechanical transmission systems. We will represent it by the standards of technical drawing and select the necessary views for definition.
We continue with 3d mechanical parts, increasingly complex, for implementation by the standards of technical drawing: A normalized representation exercise anchors support for other parts to a bench.
The arc geometry applications capable of an angle on a given segment are many and varied:
From the proof of a theorem, the intermediate solution of a problem or direct application in a case, We can see this construction repeatedly widespread.
When defining a beam circumferences as an infinite set simply fulfilling a restriction on the power, sorted the beams depending on the relative position of its elements.
Hyperbolic circumferences beams are among these families circumferences. Of the three existing (Elliptical, parabolic and hyperbolic) are those that offer greater difficulty in its conceptualization to come not defined waypoints. We will see how to determine elements that belong to them as it did in the previous cases.

Any of the problems of tangents that are included under the denomination of “Apollonius problems” can be reduced to one of the studied variants of the most basic of all: the fundamental problem of tangents (PFT).
In all these problems we will consider fundamental objective to reduce the problem to propose to one of these critical cases, by changing the constraints that define other concepts based on the orthogonality.
In this case we will study what we call “Case Apollonius RCC”, namely, For the problem of tangency at which the data are given by condition of tangency to a line (r) and two circles (cc).
Solution to the thirteenth piece of technical drawing.
They have represented the three main views (plant, elevation and profile) conducting student leaving the new views (not necessary for the representation of the object).
Between the two possible profiles, We used one containing a smaller number of hidden lines.
Solution to the fourth piece of technical drawing.
They have represented the three main views (plant, elevation and profile) conducting student leaving the new views (not necessary for the representation of the object).
Between the two possible profiles, We used one containing a smaller number of hidden lines.
Solution to the third piece of technical drawing.
They have represented the two main views (elevation and profile) leaving the student carrying a plant that completes the third projection (not necessary for the representation of the object).
